SLEIGl-l-SHOE.

Specification of Letters Patent.

Application filed August 4, 1905. Serial Na 272,755.

Patented Oct. 9, 1906.

I all whom it may concern.-

Beit known that I,CLAYTONL.CLARK, a citizen of the United States, residing in- Scott township, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Sleigh-Shoe, of which the following is a specification.

This invention relates to a sleigh-shoe.

It is the object of the invention in a ready, feasible, practical, and novel manner to assemble a cast-iron tread with a wrought iron or steel body in such manner as to prevent separation of the tread from the body should it crack, whereby the life of the shoe is measurably increased and its usefulness largely enhanced.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel form of sleigh-shoe hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate correspondparts, Figure 1 is a perspective view of a portion of the shoe. Fig. 2 is a longitudinal sectional view taken on the line 2 2, Fig. 1. Fig. 3 is a transversesectional view taken on the line 3 3, Fig. 2. Fig. 4 is a perspective detail view of the body, and Fig. 5 is a detail view showing the manner of effecting the assemblage of the shoe and body.

In carrying the invention into effect a body or cap is forged in any suitable manner, with its flanges 11 inclined toward each other to form a dovetailed channel 12, ex-

' tending longitudinally of the entire length of the body, the latter being provided with pour-holes 13, arranged at any referred distances apart and being preferably elongated and countersunk or beveled, as at 14. The cap 10 has combined with it intermediate of the holes 13 studs 17, that have their ends riveted in suitable orifices in the cap and are formed with enlarged cone-shaped heads 18, that operate to bind the tread 16 more firmly and securely to the cap.

In making a shoe as above described the the bottom thereof, as shown in Fig. 5, and the molten Inetal'to form the tread 16 is then poured in the mold and incloses the heads 18, fills the holes 13 and the channel 12, and thereby effects a firm assemblage or anchoring together of the parts. It will of course be understood that the mold is shaped to define the tread portion of the shoe.

I claim- As a new article of manufacture, a sleighshoe comprising a flexible body provided with orifices having inwardly-inclined walls and with cone-shaped studs, and a tread cast to the body and filling the channel and orifices and inclosing the studs.

In testimony that I claim the foregoing as my own I have hereto affixed my signature I in the presence of two witnesses.
